Hi, I'm a German student in physics. something i noticed is that in every theory we start with a few postulates and conclude predictions about the behaviour of uninlevend objects. Even in quantum- mechanics we can make declarations about things our mind can't even imagine (like electrons). We do all this with math or let's say logic. and here is my question. Why does the universe behave in a logical way? is logic something humans have learned from the universe and only exists in this universe or is logic something that would exist even if this universe wouldn 't exist?
and excuse my bad grammar
